The former 'I'm A Celebrity...Get Me Out of Here!' winner also confessed that the reason for her wanting to lose the weight was to "feel good" in her clothes again, having put on a stone last year after giving birth to her fifth child Dylan-Jorge with husband George Kay in April.

Speaking to Closer magazine, Kerry said: "I wanted to be healthy and feel good in my clothes again. My tummy feels firmer now, and I feel sexy and confident. My bum's perkier and my stomach is flatter, too. Given the fact I've had five kids, I think I look alright!"

Last month, Kerry - who also has children Lilly-Sue, Heidi, Molly and Maxwell from previous relationships - admitted she had confided in her Atomic Kitten bandmates that she was worried she wouldn't be able to handle the gruelling dance routines of a live show.

Her bandmate Liz McClarnon said at the time: "I broke the news to Kerry that being on tour means we will be on stage for an hour and a half without an interval, and her reaction was hilarious.

"She kept saying how exhausted she is going to be and she's worried it will be harder than she remembers from before."
